BMW 440I vs Denza B8

What's the difference?

Is now the right time to buy a 4 Series coupe? With the next-generation model a matter of months away, probably not.

That said, those buyers who decide to park a new ‘old’ 4 Series coupe in their driveway will be very pleased with their purchase.

At the end of the day, the current-generation model is still a cracking sports-luxury coupe, and more so when in 440i form. It’s just that good.

The Denza B8 is an incredibly luxurious car that has a lot going for it, including three rows of seating, a 3.5-tonne braked towing capacity and an eye-popping price tag, but it's held back by its overall heft and cumbersome ride.

If you don’t absolutely need the third row of seating, the smaller B5 is arguably the better pick and while it’s also not perfect, it’s a very compelling package and you’ll be saving thousands of dollars in the process.

The first-generation 4 Series coupe has aged relatively well, despite sharing most of its design cues with the superseded sixth-generation 3 Series sedan.

Compared to current BMW models, the 4 Series coupe’s signature kidney grille is small, flanked by angry-looking adaptive headlights with hexagonal daytime running lights, all of which are of the LED variety.

The 440i’s standard M Sport body kit adds to the aggressive styling with chunky front bumper with three large air intakes, the outer two of which also contain the LED fog lights.

Around the side, a strong shoulder line stretches from the front wheel arches to beyond their rear counterparts, while BMW’s Air Curtains split the difference between it and the sporty skirts.

The rear end is the 440i’s simplest angle, although its bumper is spruced up with a dark-grey insert and dual exhaust tailpipes. Predictably, L-shaped LED tail-lights punctuate the styling at the rear.

Inside, the 4 Series coupe is holding up well, but it's still clearly a generation behind most other new BMW models.

That said, it’s a throwback we quite like, particularly iDrive6, which is still arguably BMW’s best multimedia system to date. Powering a floating 8.8-inch touchscreen in this instance, it’s just so intuitive, partly thanks to its rotary controller.

An 8.8-inch digital instrument cluster is a late-life addition for the 440i, and while it looks great with its drive mode-specific views, it lacks the breadth of functionality of Audi’s set-up.

The 4 Series coupe’s cabin is otherwise pretty basic despite its apparent emphasis on sportiness, although the selection of luxurious materials used throughout is top-notch.

The entire dashboard, chunky M Sport steering wheel and old-school handbrake lever are trimmed in high-quality leather, while lower-quality Dakota leather covers the sports seats, armrests and door inserts.

Soft-touch plastic is used for the door shoulders and bins, even in the second row, while hard plastic is limited to the centre console, and gloss-black trim is used on the centre stack’s audio and dual-zone climate control surrounds.

There’s no way around it, the Denza B8 is a big car. It’s almost 5.2 metres long which makes it larger than a LandCruiser 300 Series and more in line with the likes of the Land Rover Defender 130.

It looks quite boxy and tough on the outside, though it doesn’t have any features that define it specifically as a Denza beyond the inconspicuous badging. There are many angles that are reminiscent of the aforementioned Defender.

The body lines look crisper than the smaller B5, as does the semi closed-off grille and LED light script that connect the big LED headlights.

Unlike the B5, the tailgate-mounted spare wheel is much more prominent in the B8 and this therefore exaggerates its heft, not in a good way.

Inside, it’s luxurious and high-end with lots of visual appeal. I particularly like the amount of soft-touch finishes around the cabin and the overall lack of glossy piano black.

While luxurious, there’s also a rugged edge to the interior. This is most present in the large grab handles which you do need to use when getting in and out.

The amount of physical buttons and switches inside is a nice touch as you don’t need to relate on the touchscreen all the time. The fact the gear shift lever rises up when you turn on the car also adds to the special, luxurious feel.

Measuring 4640mm long, 1825mm wide and 1377mm tall, the 440i coupe is a true mid-sizer, and that means it’s surprisingly practical – for the most part.

Cargo capacity is more than solid, at 445L, but stow the 60/40 split-fold rear bench via a pair of manual latches located in the boot and more storage space is quickly liberated.

To make matters even better, the boot has two bag hooks and four tie-down points, making securing a load a cinch. That said, the high load lip means bulkier items can require a little more effort to accommodate.

Up front, the door bins are large enough for a regular bottle each, while a pair of cupholders separate the gear selector from a seriously shallow storage tray.

The central storage bin is on the shallow side, too, albeit not to the same degree as the dedicated storage tray. That said, much of its space can be taken up by the optional wireless smartphone charger ($200), which was fitted to our test car.

The glovebox tries its best to make up for the lack of genuine in-cabin storage options by being quite large, while storage nets are attached to the backs of the front seats.

Rear occupants can also make use of a large storage tray that resides where a middle seat would otherwise go. They also have access to a fold-down central armrest that incorporates two more cupholders.

Speaking of armrests, the rear side ones are incredibly narrow, leaving tired elbows in a bit of a pickle.

It’s not all bad news in the second row, though, as legroom and toe-room behind our 184cm driving position are very generous, with the former offering several inches of wriggle room.

We’d go as far as to say the rear quarters are comfortable, but that would require ignoring the fact that headroom is seriously compromised with the optional power-operated sunroof ($3000) fitted, with our head pressed firmly against the 440i coupe’s Anthracite roofliner.

Either way, child seats can be fitted in the second row, with ISOFIX anchorage points available for the outer seats. Speaking of which, it’s worth noting ingress and egress to the rear bench isn’t too bad, with the front seats folding forward via manual latches.

Connectivity-wise, two USB-A ports are found in the first row, split between the centre stack and the central storage bin, while three 12V power outlets are spread across the front and rear of the centre console, and the boot.

Hopping into the B8 you need to acquaint yourself with how the flush door handles operate. Generally they pop open when you unlock the car but sometimes they can be a little delayed.

Also inside the car there are electronic door release buttons which are nowhere near as intuitive as regular door pull handles. Sure you’d likely get used to this over time but you’ll need to explain it to new passengers all the time.

The seats in Chinese cars usually look nice but aren’t that comfortable or supportive for long-distance journeys. The B8’s are the opposite, offering great support and almost limitless adjustability. Adding to this is the standard heating, ventilation and massage functions.

Ahead of the driver is a leather-wrapped steering wheel which feels nice and has plenty of physical buttons with a tactile click when pressed.

Behind this, the digital instrument cluster is clear and high-resolution and offers a number of different layouts and informative pages you can cycle through. This allows you to customise the display.

In the centre of the dashboard is the mammoth 17.3-inch touchscreen multimedia system which is the largest central screen I have seen in a car to date. It’s a big screen for a big car and Apple CarPlay satisfyingly takes up the entire screen.

Thankfully, the screen is snappy and has a native user interface that is easy to navigate around without getting lost. I particularly like the swipe-down control centre menu that allows you to change key settings without diving into sub-menus.

My only hassle with the screen is I struggle to reach the far left-hand side due to its overall size. Perhaps a trackpad would solve this.

As I noted previously, the amount of physical switchgear around the cabin makes adjusting key functions easy. Examples include physical buttons to change the drive mode, activate the surround-view camera, adjust the suspension position and switch between EV and hybrid driving.

In terms of storage up front there are two non-ventilated 50W wireless phone chargers, two cupholders with adjustable depths, a shallow storage section under the centre console, plus a fridge/hotbox under the centre armrest.

Moving to the second row and the luxury continues. The seven-seat model features a three-seat bench that three people can easily fit across as the floor is flat, whereas the six-seat model gets uber-plush captain’s chairs.

Regardless of variant, there’s plenty of room in the second row, even for adults.

Second-row amenities include a small screen on the back of the centre console box that allows you to change the climate control and change the seat heating/ventilation, among other functions.

There’s also a button that opens the fridge/coolbox so the second-row passengers can access it. This is a nifty touch though you’d want to make sure small fingers don’t get caught as the anti-pinch function isn’t the strongest.

A feature that’s unique to the six-seat version is a massaging function on the second-row captain’s chairs. This is a very cool touch that no other SUV at this price point offers.

Accessing the third row in the six-seat version is rather easy as you only need to walk down between the captain’s chairs. It’s also simple enough in the seven-seat version as long as you access it from the kerb side.

Third-row space is decent for adults, but this shouldn’t be surprising as the B8 is such a hulking vehicle. The backrests also recline allowing for extra comfort. Amenities include air vents in the headliner, USB-C ports and scattered storage. It’s enough for seats that will likely only get occasional use.

Around the back the B8 has a side-hinged tailgate which is a little problematic as you need to allow space for it to open up in parking spaces. This is hard when the car is already 5.2m long…

With all three rows upright there is 147L of boot space, which is fine, but this expands to a much more usable 920L with the third row folded.

The boot space is square and usable, though there is a large load lip which is body-coloured and would easily get scratched if you drop something on it. Not the best in a family-oriented vehicle.

Boot-related amenities include buttons to electronically fold the second and third row seats and lower the suspension to make things easier to load into the boot, a 12V socket, scattered hooks, as well as a small underfloor section to store the changing cables.

Although it stands out like a sore thumb, it’s great to have a full-size spare wheel on the back of the tailgate. This is very helpful in the unlikely and unfortunate event you get a puncture.

The 2026 Denza B8 line-up starts at $91,000, before on-road costs, for the seven-seat version, which is strategically just under the Luxury Car Tax (LCT) threshold, whereas the flagship six-seat version is $97,990, before on-road costs.

Despite nearing $100K, this notably undercuts key rivals like the Toyota LandCruiser 300 Series and Land Rover Defender by a considerable margin, especially once you take the level of standard equipment into account.

The B8’s closest rival is currently the slightly smaller GWM Tank 500 PHEV which is priced even more competitively at $77,990, drive-away.

As a base there are 20-inch alloy wheels, adaptive LED headlights, soft-close doors, a 12.3-inch digital instrument cluster, a 17.3-inch touchscreen multimedia system, 18-speaker Devialet sound system, tri-zone climate control, leather upholstery, plus heated and ventilated seats in the first and second row.

Moving up to the six-seat version brings second-row captain’s chairs with adjustable legrests and a massage function, as well as a digital rear-view mirror, head-up display and Nappa leather upholstery.

This amount of standard equipment in a car that’s under $100K is wild and should definitely be enough to put in your consideration list if you’re after a big, three-row SUV. The smaller B5 offers similar levels of specification but goes without the third row.

The 440i coupe is motivated by a silky smooth 3.0-litre turbo-petrol in-line six-cylinder engine that punches out 240kW of power at 5500rpm and 450Nm of torque from 1380-5000rpm.

An equally silky smooth eight-speed torque-converter automatic transmission exclusively sends drive to the rear wheels – a characteristic that has become a rarity in this segment.

This combination helps the 440i coupe sprint from a standstill to 100km/h in a scant five seconds flat with launch control engaged, according to BMW. Its top speed is electronically limited to 250km/h.

Power comes from a plug-in hybrid set-up combining dual electric motors and a 2.0-litre turbo-petrol four-cylinder engine.

Total system outputs are a meaty 425kW and 760Nm. They need to be, as the B8 has a kerb weight of 3.3 tonnes. Despite this, Denza claims it can still do the 0-100km/h sprint in just 4.8 seconds.

Power is sent to all four wheels with a rear mechanical diff lock as standard across the line-up. A front diff lock is only offered on the six-seat version.

What’s most surprising about this big beast is it offers a segment-meeting 3500kg braked towing capacity. It also has up to 700kg of payload, depending on the variant.

The 440i coupe will drink a claimed 6.8 litres per 100 kilometres on the combined cycle, while its carbon dioxide emissions are 159 grams per kilometre.

Our week of testing skewed towards city driving over highway stints, and we averaged 8.6L/100km, which is impressive given the six-cylinder performance on offer. And yes, we did put it to use...

The 440i coupe's 60L fuel tank takes 95RON petrol at minimum.

Feeding the dual electric motors is a 36.8kWh lithium iron phosphate (LFP) battery. Denza claims it allows for an electric range of 115km, according to NEDC testing.

The battery can also be used as a power source for appliances using vehicle-to-load (V2L) functionality at rates up to 6.6kW.

AC charging is offered at rates up to 11kW, whereas DC fast-charging is offered at rates up to 120kW.

Additionally, there’s a 91L fuel tank. Denza claims this allows the B8 to have a total range of 1040km (NEDC).

Fuel consumption depends on how often you charge the battery. Denza claims the B8 will use 2.0L/100km from 100 to 25 per cent battery charge and 9.9L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than all similarly sized petrol- or diesel-powered SUVs.

The 440i coupe toe the line between sports car and luxury vehicle very, very well.

The straight-line performance is definitely there thanks to its in-line six-cylinder unit, which is one of our favourite engines in any vehicle – period.

From top to bottom, the 3.0-litre unit is absolutely delicious. Maximum torque kicks in just above idle and remains on tap deep into the top end, at which point a fleeting moment of peak power is just 500rpm away. Needless to say, acceleration is strong.

Remarkably, the engine’s twin-scroll turbo exhibits next to no lag, making for a unit that you truly want to wring out. That said, don’t expect aural pleasure when you do so, as the sound it generates is lacklustre. Yep, no enticing crackles or pops are heard here.

The automatic transmission ties everything together beautifully, providing timely, quick and smooth gear changes on the regular, even without its Sport mode engaged. And, of course, there are paddle-shifters on hand if you want to take matters into your own hands – literally.

Given the 440i coupe’s apparent performance bent, you’d be forgiven for thinking it rides like an unforgiving sports car. Well, the good news is it doesn’t.

Consisting of MacPherson-strut front and multi-link rear axles with adaptive dampers, its independent suspension set-up stands up really well to Australian roads.

While potholes and coarse-chip roads would usually be met with hesitation, the 440i coupe silences the doubters with its composed ride. Can you feel them? Yes, but they’re relatively muted, especially in a car with sporty aspirations, like this one. 

Cornering is a lot of fun, too, thanks to excellent body control. Tip its 1555kg kerb weight into a corner with intent and you’re quickly reminded why SUVs are nowhere near this fun to drive.

Simply put, the 440i coupe loves a twisty stretch of road, where its M Sport brakes (front: four-piston fixed callipers, rear: two-pot floating stoppers) and traditional rear-wheel-drive dynamics come out to play.

This experience is enhanced by its superb electric power steering, which is speed-sensitive, meaning it’s quick at low speed, for improved manoeuvrability, and ‘slow’ at high speed, for improved stability.

We absolutely adore this particular system, mainly because of its perfect weighting and surprising amount of feel. And in a surprise to no-one, it also turns in really well, too.

Of course, if you want to take the 440i coupe’s handling to the next level, you can engage its Sport drive mode, which stiffens up the adaptive dampers for even flatter cornering and adds more heft to the electric power steering. But we’d say both are unnecessary.

Behind the wheel, the Denza B8 primarily acts as an electric vehicle (EV), meaning it’s largely quiet inside the cabin when driving around normally.

Once the battery charge gets down lower, the petrol engine typically switches on to top up the battery. It largely acts as a generator and a lot of the time you can’t tell whether it’s on or off.

You’ll likely only notice it if you floor the accelerator or go up a steeper hill. Even then the engine largely stays quiet and in the background.

When the battery charge gets down low enough and you gun it, the petrol engine can directly power the front wheels. This is rare, though, because the car leaves at least 25 per cent battery charge in reserve.

With 425kW and 760Nm thanks to the dual electric motors and 2.0-litre turbo-petrol engine, the B8 is far from slow. In fact, for a 3.3-tonne beast it absolutely hauls thanks to the instantaneous torque the electric motors provide.

However in the standard drive mode there is a noticeable input lag from when you push the accelerator pedal hard and when the car starts accelerating. This is reduced in the 'Sport' drive mode.

Although the B8 may produce lots of power and torque, it feels its weight. When you accelerate hard it pitches back dramatically, much like the Jeep Grand Cherokee. It’s much more pronounced than in the smaller B5, but still smile-inducing.

As standard, the B8 line-up gets an adaptive hydraulic suspension system that is claimed to be able to self-level the car. Despite this, the B8 gets a considerable amount of body roll regardless of which drive mode you select.

Many Chinese cars have floaty, comfort-oriented suspension tunes over firmer and a more dynamic-feeling ride, and the B8 is no exception. It feels like a 3300kg+ SUV.

The kicker is, like many body-on-frame vehicles, the ride gets busy on harsher roads with more frequent bumps. As a passenger you get jostled about in the cabin.

The steering tries to disguise the overall heft of this SUV but as a result it can feel overly assisted and vague at certain points. Depending on the drive it either artificially adds or reduces resistance.

Unlike the related BYD Shark 6, the B8 gets diff locks and a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled, low-speed crawling.

The adaptive hydraulic suspension allows the car to be lowered down or lifted up. In its highest mode there is a 890mm maximum wading depth.

Interestingly, compared to the smaller B5, the B8 feels more sorted off the beaten path. Its added heft helps round off bumps more easily, plus there’s added momentum behind it.

Lastly, in terms of noise, vibration and harshness (NVH), the B8 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.

Surprisingly, given the B8 is a huge 3.3-tonne box on wheels, there is very little road and wind noise. It seems Denza has put a big emphasis on sound insulation.

The Denza B8 received a maximum five-star ANCAP safety rating based on testing conducted on the related B5 in 2025.

There are 14 airbags which notably includes coverage for the third row, plus autonomous emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control, front and rear parking sensors and a surround-view camera.

The majority of the active safety systems do a good job, remaining in the background and only activating when absolutely necessary. However, the driver attention monitor is over zealous and struggles to detect your eyes when you’re wearing sunglasses.

Thankfully, you can turn this off using the touchscreen but it needs to be done every single time you drive the car.

As with all BMW models, the 4 Series comes with a three-year/unlimited-kilometre warranty with three years of roadside assistance, both of which are two years short of the premium standard now set by Mercedes-Benz.

The 440i coupe’s service intervals are every 12 months or 15,000km, whichever comes first. Owners can opt for a $1650 five-year/80,000km capped-price servicing plan, which is well-priced.

The Denza B8 is covered by a six-year, 150,000km warranty, whereas the battery pack is covered by an eight-year, 160,000km warranty. There’s also three years of roadside assistance.

This isn’t a standout warranty in the mainstream market, though compared to premium marques it’s a notable step up.

Logbook servicing is required every 12 months or 20,000km, whichever comes first.

The first five years' of servicing totals $3762, which averages out to just over $750 per service. This is just a tad more than the smaller B5, but it’s much cheaper than premium rivals.
